Abstract: 844,195. Collating record cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 24, 1957 [Dec. 31, 1956], No. 40011/57. Class 106 (1). [Also in Group XVI] A record-card collator comprises separate means for feeding cards from each of two sources to spaced positions in a common feed path which includes a plurality of feeding devices each selectively operable to feed the cards selectively in opposite directions and at least two sensing stations controlling the feeding. Primary cards 12, Fig. 2, are fed from a stack 15 under sensing brushes 22, 23 to a point 24 under oppositely moving feed belts 26, 29. From this point the card is moved either to the left to point 27, whence it is passed at rightangles by pusher 28 to " primary-select " stacker 13, or to the " merge station " 31, whence it is displaced at rightangles by pusher 32 to the merge stacker 14. Secondary cards 17 from hopper 30 pass under brushes (not shown) to point 36 and are fed by belts 37 or 38 to point 33 or point 39. From point 33 the card may be advanced by pusher 34 to " secondary-select No. 1 " stacker 18 or to the merge station 31. From point 39 a pusher 41 passes the card to " secondary-select No. 2 " stacker 19. The movements of the card are controlled by electromagnets some of which are shown in Fig. 4 which shows the feed path at the points 24 and 31. A card at point 24 has edges lying under both belts 26, 29 which are constantly driven. A magnet 92 has polepieces on each side of belt 29 and serves when energized to attract rollers 158 which force the card against the belt and displace the card to the right. A similar magnet causes belt 26 to be effective to pass the card to point 27 (Fig. 2). A card moving to the right is gripped by rollers 160, 159 and advanced thereby between plates 164, 165 which constitute the merge station. A spring-loaded lever 168 carrying roller 159 has a curved end 161 which forces the card against the roller 160 to ensure that it passes fully between plates 164, 165. Cards similarly fed to the left from station 36 are either stopped at point 33 by a stop 179 or allowed to pass on to.engage between rollers 182, 183 which advance it to the merge station 31 between plates 165, 166. A spring-loaded lever 186 bears on roller 183 to ensure proper positioning of the card in the same way as lever 161. Pusher 32 is operated cyclically by a cam 194 to displace cards in the merge station to the merge stacker 14. Selected parts of the data read from the primary and secondary cards at sensing stations are entered into magnetic core matrix stores. The data is read out from these stores digit by digit and applied to comparison circuits which determine relative magnitudes of the values entered. Plug connections on a control panel govern the control magnets mentioned above to determine whether the primary card shall pass to the primary-select stacker 13 or the merge stacker 14 and whether the secondary cards shall pass to the merge stacker, the secondary-select stacker No. 1, 18 or secondary-select stacker No. 2, 19. Specifications 523,652, 770,244, 772,270 and 789,668 are referred to.
